Directions/Specifications
Airstones come with an extra middle section that was meant to be removed at the factory. For easiest fitment, remove 1 disk per air stone when installing.
Installation:
Start with a bare bottom aquarium (if you have substrate in the tank, you will need to remove it first). Lay out the modular plates based on the width of the tank bottom you want the filter to cover, then add plates in front to complete your grid pattern. The plates connect by sliding the dovetail into the corresponding tab opening.
Before connecting all of the plates, install the uplift tubes by sliding them on the sides for the row you would like them on. Install the air collar with an air stone with a short piece of
Airline tubing (if using the supplied air stone, remove 1 air stone spacer for best fit). Once the uplifts tubes have been attached, you may complete the plate connecting step. Once all the plates and uplift tubes have been connected, you can finish by covering with a gravel of your choice. We recommend using a substrate that is at least 5mm in size, and adding between 1" to 2" in depth. Please note that undergravel systems are not designed to be utilized with sand, soil, or other finer substrates.
Dimensions:
Each plate measures 2.75" x 5.5" (2 7/8" x 5 5/8" if including the dovetail tabs), and are 9/16" thick. Total dimension of the included 20 plates is 11" x 27.75". The included Easy Flow Uplift Tubes measure 19" in height, but can be added to with additional tubes for additional height if needed.
Each kit contains 20 Easy Undergravel Filter Plates. This means that one kit can work with 10 gallon tanks, 20 gallon, 29 gallon, and more. 9 plates can cover the bottom of a 10 gallon aquarium, which means that one kit can be utilized for two 10 gallon aquariums with one uplift tube for each. For larger tanks where you are wanting full coverage, we recommend two kits.
Additional Supplies Needed
The undergravel filter does not produce air on its own, so you also need to buy the following components to run this filter:
(to prevent water from pouring out of the tank when the power is off)
Cleaning Instructions:
Gravel vac normally, removing mulm (debris) from the substrate. Getting good suction and proper technique can make this much easier. This video demonstrates the best technique we know.
